“With the Sahel region being the most vulnerable and heavily affected by desertification, an initiative known as ‘The Green Wall’ was put in place for the Sahara and Sahel in 2007. Its ambitious aim is to grow an 8,000-kilometre natural wonder across the entire width of Africa in order to increase the amount of arable land bordering the Sahara desert. The idea is that planting more trees will combat desertification, create jobs, increase food security and bring migrated populations back home to Africa.”
